Fiddle: http://jsfiddle.net/ATUEx/ Create a temporary cache to remember your key strokes. An implementation of handling two keys would follow this pattern: <keydown> Clear previous time-out. Check whether the a key code has been cached or not.If yes, and valid combination: – Delete all cached key codes – Execute function for this combination else – Delete … Read more
Keep track of which keys are down, and ignore keycode 39 until a keyup even clears it: var down = {}; $(document).keydown(function(event){ var keycode = (event.keyCode ? event.keyCode : event.which); if(keycode == ’39’){ if (down[’39’] == null) { // first press $(“#box”).animate({“left”: “+=30px”}, “fast”); down[’39’] = true; // record that the key’s down } } … Read more
Have you set the KeyPreview property of the form to true? That will cause the form to get a “first look” at key events. Update: getting this to work properly when a Button has focus seems to be a bit tricky. The Button control intercepts the arrow key presses and moves focus to the next … Read more
New in SwiftUI bundled with Xcode 12 is the commands modifier, which allows us to declare key input with keyboardShortcut view modifier. You then need some way of forwarding the key inputs to your child views. Below is a solution using a Subject, but since it is not a reference type it cannot be passed … Read more
You can check the modifiers of the KeyEventArgs like so: private void listView1_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Up && e.Modifiers == Keys.Control) { //do stuff } } MSDN reference
jQuery normalizes modifier keys on events by setting one or more properties on the event object. So, you want to set event.ctrlKey to true, so this should work for you: e = jQuery.Event(“keydown”); e.which = 50; e.ctrlKey = true; $(“input”).trigger(e); However, as per a comment at source (linked below): You cannot easily change values in … Read more
If you are okay with a minimum requirement of OS X 10.6+, and can suffice with “read-only” access to the stream of events, you can install a global event monitor in Cocoa: Cocoa Event-Handling Guide: Monitoring Events. If you need to support OS X 10.5 and earlier, and read-only access is okay, and don’t mind … Read more
Whenever a cell is in edit mode, its hosted control is receiving the KeyDown event instead of the parent DataGridView that contains it. That’s why your keyboard shortcut is working whenever a cell is not in edit mode (even if it is selected), because your DataGridView control itself receives the KeyDown event. However, when you … Read more
if (e.KeyCode == Keys.C && e.Modifiers == (Keys.Control | Keys.Shift)) { //Do work } else if (e.KeyCode == Keys.V && e.Modifiers == Keys.Control) { //Paste }
Yes, indeed there is. The correct way for the form to handle key events regardless of the control that currently has the input focus is to override the ProcessCmdKey method of your form class: protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { if (keyData == Keys.F1) { MessageBox.Show(“You pressed the F1 key”); return true; … Read more
